Swedish citizens going to the US for tourism or business* and who will stay for 90 days or less might be able to travel without a visa on the Visa Waiver Program, which is administrated by the Department of Homeland Security.
When traveling on the Visa Waiver Program a general rule is that the passport has to be valid for 6 months after the return from the US. Please note that Swedish passports have a country-specific agreement and are excepted from the six month rule and can be used as long as the passport validity covers the whole stay in the US. On the State Department website you can find the full list of countries with country-specific agreement .
To be able to request admission to the US on the Visa Waiver Program, the traveler must have an approved online ESTA registration.
To apply for ESTA, please go to: https://esta.cbp.dhs.gov
